This invention appertains to new and useful improvements in furnitureand more particularly to a high chair tray and attaching means therefor.

The principal object of the present invention is to provide attachingmeans for high chair trays of such construction as to make itpractically impossible for the infant to loosen the tray.

Still another important object of the invention is to provide a safe andsubstantially fool-proof detent for high chair trays which will be ofsimple construction and of low cost to manufacture.

Other important objects and advantages of the invention will becomeapparent to the reader of the following specification.

In the drawings:

Figure 1 represents a fragmentary side elevational view of a high chairequipped with the novel tray structure.

Figure 2 represents a fragmentary inside elevational View of one of thearms of the chair.

Figure 3 is a sectional view taken substantially on the line 33 ofFigure 1.

Figure 4 is a top plan view of the attaching means detached from thetray with parts in section.

Figure 5 is a sectional view on the line 5-5 of gure 4.

Figure 6 is an edge elevational view of one of the latch members.

Figure 7 is a perspective view of the pivotal catch.

Figure 8 is a perspective view of one of the connecting rods.

Figure 9 is aperspective view of one of the keeper plates.

Figure 10 is a plan view of the operator.

Figure 11 is an edge elevational view of the operator.

Referring to the drawings wherein like nu-' merals designate like parts,it can be seen in Figure 1, that numeral 5 generally refers to a highchair which includes the legs 6 depending from the seat 1 and also theback 8 and props 9 supporting the armrest [0.

These armrests l each at its inner side is, as shown in Figure 3,provided with a longitudinally extending slot ll opening into achannelway I2 in which is secured an elongated keeper plate l3 providedat equally spaced intervals with openings l4.

Numeral l represents the tray which includes the bottom l6 and sidewalls IT. A plate I8 is suitably secured to the bottom of the tray I5and has the pocket I 9 therein for receiving the operator 20 which isprovided with a laterally extending arm 2| provided at its outer endwith the downwardly disposed finger engageable lip 22. The periphery ofthe plate 20 is notched to define the shoulder 23 against which the lip24 on the arm 25 of the pivotal catch 26 is engageable. This catch 26 isprovided with the longitudinally extending flange 21 between which and aportion of the plate l8 a coiled compressible spring 28 is interposedfor normally maintaining the lip 24 engaged against the periphery of theoperator 20 and in the path of the shoulder 23.

The end portions of the plate l8 are pocketed as at 29 for receiving thedetent arms 30.- Each of these arms consists of an elongated member 3|having upwardly disposed portions 32-32 with an ear 33 extending fromone of these portions 32 and apertured to receive the pivot member 34and its opposite end being provided with the extension 35 laterally fromwhich extends the tooth 36 for engagement into the corresponding openingM of the corresponding keeper plate I 3.

A connecting rod 31 provided with laterally disposed end portions 38 isprovided for each of the detents 30, one end of the connecting rod beingengaged with the extension of the corresponding detent 30 while itsopposite end is engaged into the corresponding slot 39 of the operator20.

A spring member 40 has its ends the upwardly disposed portions 32-32 ofeach of the detents 30 and each of the pockets 29 is provided with aboss formation 4| normally bearing against the corresponding springmember 40. Thus, the teeth 36 are normally keeper plate gripping theswinging the same so as to disengage the lip 24 40 from the shoulder 23so that the operator is freed and can be swung to retract the teeth 36from the keeper plates I3.

It can also be seen that the end portions of the plate l8 are reduced asat 42 for sliding disposi- 45 tion in the slotways ll.

While the foregoing specification sets forth the invention in specificterms, it is to be understood that numerous changes in the shape, sizeand materials may be resorted to without departing from the spirit andscope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

In combination, a high chair including arms,

connected to 30 keeper means on the inner sides of the arms, a tray,latch means on the tray including detents swingably mounted thereon forengagement with the keeper means on the arms, a rotatable operator onsaid tray operatively connected to the detents to engage and disengagethe same, and having a shoulder thereon, a catch for the operator havinga lip thereon for engagement with the shoulder to prevent operation ofthe operator, said catch being mounted on the tray and operative todisengage the lip from the shoulder, and

spring means tensioning said catch against such 5 operation.
